Line a small baking pan with parchment paper. Ensure the pan fits the air fryer basket.
Preheat the air fryer to 400°F.
Slice the zucchini into ¼" thick rounds. Place in a single layer in batches in the air fryer basket and cook for 8-10 minutes or until tender.
Reduce air fryer temperature to 350°F.
Meat Sauce
While the zucchini is cooking, heat a frying pan over medium heat. Add the ground beef, onions, and garlic and cook until no pink remains. Drain any fat.
Add the pasta sauce and Italian seasoning to the ground beef and simmer for 2 minutes.
Cheese Sauce
In a medium bowl, mix the ricotta cheese, parmesan, egg, basil, parsley, salt, and pepper.
Assembly
Spread ½ cup of meat sauce onto the bottom of the baking pan.
Layer half of the zucchini slices and half of the remaining meat sauce. Top with all of the ricotta mixture.
Top with the remaining zucchini and finish with the remaining sauce.
Cover the lasagna with foil and bake for 40-50 minutes or until cooked through. Remove foil and sprinkle mozzarella cheese over the top. Bake for an additional 8-10 minutes until cheese is golden brown.
Rest at least 15 minutes before serving.
Notes
Additional beef can be added for a meatier sauce.Zucchini contains a lot of water, cooking it first helps keep the dish from being watery. As it rests, the lasagna will release a bit of water.
